SHUTTLE PLACER FOR' LOOMS.

' This invention relates to improvements in shuttle placers for looms and an object of the inventionis to provide a device of this kind which shall be very strong and positive in its placing action but which will move forwardly against comparatively light resistance when engaged by a shuttle too widely misplaced to be moved into the box.

In application Serial No. 496,351 there is shown a shuttle placer roll rotatably mounted on a slide held rearwardly by a strong spring. IVhen a widely misplaced shuttle is presented to the roll the latter will engage the front wall of the shuttle and be moved bodily forward against the spring, but if the shuttle is only slightly misplaced the roll will engage the rounded end of the shuttle and will push the latter into the box by a rolling action. The spring which holds the roll rearwardly must necessarily be of considerable strength to overcome the friction of the shuttle binder against the shuttle as the latter isboxed and I have found that where a shuttle is misplaced widely enough to cause the roll to engage one of the thin walls of the shuttle, the lattcr is likely to be crushed by the action of the spring. I

It is the general obiect of my present 111- vention to lessen the pressure against a widely misplaced shuttle and in carrying my invention into effect I provide the slide on which the roll is mounted with a comparatively light spring and make provision for a lateral movement of the slide to bring the latter into engagement with a fixed abutment when the roll engages a slightly misplaced shuttle. When the roll engages a widely misplaced shuttle there will be no lateral displacement of the slide and therefore the latter can move past the abutuient without engaging the same.

It is a more detailed object of my invention to provide a placercapable of assuming' two different positions and remaining normally in one position when not placing and moving to the other position when placing a shuttle. l 'VVith these and other objects 111 new which .will appear as the description proceeds, myinvention resides'in the combination I and arrangement of parts hereinafter 'described and set forth in the claims.

1 In the accompanying drawings,

Fig. 1 is a top plan view of my improved placer,

F 1g. 2 is a diagrammatic view showing the action of the placer when engaged by a w dely misplaced shuttle, and

Fig. 3 is a view similar to Fig. 2 but with the placer in engagement with a slightly misplaced shuttle.- 1

Referring to the drawings it will be seen that I haveiprovided a breast beam 10 on which is mounted a stand ll-having a guideway 12 thereinfor the side filling stop' mo t1on slide 13. A stand 14 extends from the breast beam and has pivoted thereto a knock off lever 15, .one end of which is positioned for dislodgingthe' shipper handle 16 from notch 17 formed in the casting 14 to stop the loom: The inner end of lever is made in the form of a cylinder. 18 in which is slidably mounted a plunger 19 having an enlarged head 20 projecting beyond the cylinder and held in such position by a coil spring 21. A cotter pin 22 passing through the plunger and engaging the lever limits movement of the head 20.

In carrying out my invention Iform the stand 11- with walls and 31, between which is an upstanding guide 32. A slide 33 moves freely betweenthe. walls and is held 'in place by a rod 34 having the ends thereof received in the slide-and passing through said guide 32. The rod is held to the slide by a set screw 35.

Ahead 36 is pivoted as at 37 on the slide 34. and has a forwardly extending tail 38 which permits angular adjustment of the head-by means of screws'39 and 40, respectively, which are mounted on the slide. A roll 41 adapted for engagement with the shuttle is rotatably mounted on a pin 42 carried by the head 36. The matter thus far described is substantially the same as set forth in the aforesaid application, Serial No. 496,351.

My invention relates more particularly to making provision for varying the resistance which the placer aifords to a misplaced shuttle and -I accordingly provide the slide '34 with a shoulder '50-, making that portionof 'the slide immediately in front of the shoulder narrower than the forward endther'eof so that the slide may-- Swing through a slight angle about the upstanding'guide- 32. The rod 3.4 fits the guide 32 loosely enough t rmit 1 h angplar motion. v'llhe slide is normally held .in the pcsltionj shoyyn in Fig. l by means of a spring 51 haying 3' eat code? .rh h pqsiti ned o s i n cured ito'thezs tand hyimeans-ot the boltls56 which hold the stand to the .breas't beam, and said plates extend over theslide i33iancl'help to prevent upward movement thereof.

Under normaloperation the shuttle S will be properly Ibozed andwil'l mone'itorward beyond the 110113 31 without engagi-ngthe same, but if the shuttle shouldbe widely misplaced as indicated in Fig. 2 fihQlfI-Olll', Wall of the shuttle will engage the roll 41=and the slide 33 will be moved forwardly-against the action of light spring 54 and engage plunger 20. to swing th'elever 15 :to stop theloom. This forward imotion will be accompanied oy-snch a light pressnre as willrnot endanger the'shuttle Shonld'th shnttle'be slightly misplaced, however, asshoivn-inf Fig; E},-=it will more therollc tlto the left against the action of spring fil'because of theofact that said roll will engage the rounded-part 0f the shuttle. 7

This will bring the shoulder 50 opposite the rear portion'o; wallfiO so as'to prevent forward inotioni'ot' :the' slide. -;l3he roll A1 is therefore required to move aboutffixed Taxis 37and place 'the'shuttle. It will benoted that the lateral "movement to bring the shoulder againsfla-fixed stop occurs only when it is Lossible-to-place the shuttle .due to thecngagem'ent of 'the' ronnded end of the latter with thei'roll. While I have shown the walls 30 and Blaspafiallel and the slide 33 tapered,' yet I' do'not Wish to'he limited to this construction, as it will sufiice to employ any arran ement git-the parts which will permit the is ionlder 50 to move into engaging position with a fixedstop;

Fromth'e fioregoing it will be seen that I have provided a shuttle placer which is capable of assuming-two lateral positions depending upon the extent to which the shuttle .i gnisplaeed. "Ifthe. shuttle-"is so v'ide'ly misplaced as to-h'nin a weakened portion tliretifzoppesite-the' oil the latter tviil' moxie tomaifdly' against the action of the eomoarativelyslightsspring 54 It the shuttle I only slightly misplaced so that the roundeden'c} thereofi engages the roll the new will be 'g wea e nightmare dis lacement which will preyient ,fnrther torward incitement of the roll, thus requiring placing of the sl iuttle.

Having thus described ,my invention it will be apparent that changes and modifications may be made thereinby those skilled in the art Without departing from the spirit 113; sc ope.of tl ie invention, and I do not Wish to be limited to the details herein disclosed, but what I claim is;

1. In a loom, a shuttle placer normally inopertine when the shuttle is properly placed and receiving a shuttle placing movement by engagement with ;a misplaced shuttle, said placer being movable forwardly with a widely misplaced shuttle, and movable laterally by a slightly misplaced shuttle, and means to arrest forward motion of the placer when moved laterally. 2. In a loom, a shuttle place-r normally inoperative when t-heshuttle is properly placed and-receiving a shuttle placing movement by engagement with a misplaced shuttle, said placer being movable to assume two lateral positions, said placer assuming one or the other of said positions depending upon whether the shuttle be slightly of widely misplaced, said placer when in the position corresponding to a slightly misplaced shuttle haivlng a-placing' action-and when in the position correspo,nding to a Widely misplaced shnttle being yieldable Without 113V? ing a placing action.

3. In a loom, a shuttle placer normally inoperative When the shuttle is properly placed and receiving a shuttle placing movementby engagement with a misplaced shuttle, means to hold the placer yieldingly in normal position and permitting lateral movement of the placer when-the latter is engaged by aslightly misplaced shuttle, and meansto arrest forward movement of the placerwhen the latter is moved laterally.

4. In a loom, a shuttle placer normally at rest and receiving a shuttle placing movement by engagement with a misplaced shuttle, a slide on which said placer is mounted capable of assuming-two positions, relatively light resilient means to resist forward movement of the slide when in one pos tion, and meansto positively prevent forward. movement-oi the slide when in the other position.

5. In a loom, a shuttle placer normally at restand receiving a shuttle placing movement by engagement with a] misplaced shuttle, a slide on which saidplacer is mounted, a guide in which said slide is loosely mounted, said slide being capable of ascoming two positions in said guide, means to pemnit yielding forward movement of the slide when in the other position.-

6 in a'loorma shuttle plaeernormally in operative when the shnttl is properly placed h v nga shuttl p ecing 'IL' when engaged by a misplaced shuttle, said shuttle placer being capable of assuming two positions and movable when in one of said positions with a widely misplaced shuttle without placing the latter and held against motion with a slightly misplaced shuttle when in the other position to have a placing movement.

7. In a loom, a shuttle placer normally at rest and having a shuttle placing movement when engaged by a misplaced shuttle, a slide on which said placer is mounted, a guideway for the slide having walls in which said slide is loosely fitted to permit lateral movement of the slide, resilient means acting laterally against the slide to move the latter against one wall of the guideway, and means formed on the slide to engage the other wall of the guideway when the slide is moved laterally against said resilient means to prevent forward movement of the slide in the guideway.

8. In a loom, a shuttle placer normally at rest and having a shuttle placing movement when engaged by a misplaced shuttle, a slide on which said placer is mounted, a guideway for the slide in which the latter is loosely fitted, yielding means to hold the slide rearwardly, resilient means to hold said slide normally against one side of the guideway and permitting movement of the slide on the other side of the guideway to allow the slide to assume two lateral positions, a shoulder formed on the slide normally movable in a path out of alignment with one side of the guideway and movable into alignment with said last named side of the guideway when the slide moves to the other position to arrest forward movement of the slide.

9. In a loom, a shuttle placer normally at rest and having a shuttle placing movement when engaged by a misplaced shuttle, a slide on which said placer is mounted, a guide for said slide permitting the latter to assume two positions, and co-acting abutments formed on the slide and the guide, said abutments being out of alignment when the slide is in one position to permit the same to move forwardly and being in engaging position when the slide is in the other position to prevent the slide from moving forwardly.

In testimony whereof I have hereunto affixed my signature.

RICHARD GREENLEAF TURNER.
